CertCentral Services API: Keep the "www" subdomain label when adding a domain to your account
To give you more control over your domain prevalidation workflows, we added a new optional request parameter to the Add domain API endpoint:
keep_www. Use this parameter to keep the www. subdomain label when you add a domain using a domain control validation (DCV) method of
By default, if you are not using file-based DCV, the Add domain endpoint always removes the www. subdomain label from the
name value. For example, if you send www.example.com, DigiCert adds example.com to your account and submits it for validation.
To keep the www and limit the scope of the approval to the www subdomain, set the value of the
keep_www request parameter to true:
CertCentral: Bulk domain validation support for DNS TXT and DNS CNAME DCV methods
DigiCert is happy to announce that CertCentral bulk domain validation now supports two more domain control validation (DCV) methods: DNS TXT and DNS CNAME.
Remember, domain validation is only valid for 397 days. To maintain seamless certificate issuance, DigiCert recommends completing DCV before the domain's validation expires.
Don't spend extra time submitting one domain at a time for revalidation. Use our bulk domain revalidation feature to submit 2 to 25 domains at a time for revalidation.

CertCentral: DNS CNAME DCV method now available for DV certificate orders
In CertCentral and the CertCentral Services API, you can now use the DNS CNAME domain control validation (DCV) method to validate the domains on your DV certificate order.
Note: Before, you could only use the DNS CNAME DCV method to validate the domains on OV and EV certificate orders and when prevalidating domains.
To use the DNS CNAME DCV method on your DV certificate order:
Note: The AuthKey process for generating request tokens for immediate DV certificate issuance does not support the DNS CNAME DCV method. However, you can use the File Auth (http‑token) and DNS TXT (dns‑txt‑token) DCV methods. To learn more, visit DV certificate immediate issuance.

Industry changes to file-based DCV (HTTP Practical Demonstration, file auth, file, HTTP token, and HTTP auth)
To comply with new industry standards for the file-based domain control validation (DCV) method, you can only use the file-based DCV to demonstrate control over fully qualified domain names (FQDNs), exactly as named.
To learn more about the industry change, see Domain validation policy changes in 2021.
How does this affect me?
As of November 16, 2021, you must use one of the other supported DCV methods, such as Email, DNS TXT, and CNAME, to:

CertCentral: Pending certificate requests and domain prevalidation using file-based DCV
Pending certificate request
If you have a pending certificate request with incomplete file-based DCV checks, you may need to switch DCV methods* or use the file-based DCV method to demonstrate control over every fully qualified domain name, exactly as named, on the request.
*Note: For certificate requests with incomplete file-based DCV checks for wildcard domains, you must use a different DCV method.
To learn more about the supported DCV methods for DV, OV, and EV certificate requests:
If you plan to use the file-based DCV method to prevalidate an entire domain or entire subdomain, you must use a different DCV method.
To learn more about the supported DCV methods for domain prevalidation, see Supported domain control validation (DCV) methods for domain prevalidation.
